HELP Help
DO Do
F6-F20 F6-F20
On LK201 keyboards:
o You cannot define keys F1 to F5 or the arrow keys (E7 to E10).
o You can define keys F6 to F14 only if you have first entered
the DCL command SET TERMINAL/NOLINE_EDITING. In that case, the
line-editing functions of the left and right arrow keys (E8
and E9) are disabled.
equivalence-string
Specifies the string to be processed when you press the specified
key. Typically, this is one or more debugger commands. If the
string includes any space or nonalphanumeric characters (for
example, a semicolon separating two commands), enclose the string
in quotation marks (").
2 – Qualifiers
2.1 /ECHO
/ECHO (default)
/NOECHO
Controls whether the command line is displayed after the key has
been pressed. Do not use /NOECHO with /NOTERMINATE.
2.2 /IF_STATE
/IF_STATE=(state-name[, . . . ])
/NOIF_STATE (default)
Specifies one or more states to which a key definition applies.
The /IF_STATE qualifier assigns the key definition to the
specified states. You can specify predefined states, such as
DEFAULT and GOLD, or user-defined states. A state name can be
any appropriate alphanumeric string. The /NOIF_STATE qualifier
assigns the key definition to the current state.
2.3 /LOCK_STATE
/LOCK_STATE
/NOLOCK_STATE (default)
Controls how long the state set by /SET_STATE remains in effect
after the specified key is pressed. The /LOCK_STATE qualifier
causes the state to remain in effect until it is changed
explicitly (for example, with a SET KEY/STATE command). The
/NOLOCK_STATE qualifier causes the state to remain in effect
only until the next terminator character is typed, or until the
next defined function key is pressed.
2.4 /LOG
/LOG (default)
/NOLOG
Controls whether a message is displayed indicating that the key
definition has been successfully created. The /LOG qualifier
displays the message. The /NOLOG qualifier suppresses the
message.
2.5 /SET_STATE
/SET_STATE=state-name
/NOSET_STATE (default)
Controls whether pressing the key changes the current key state.
The /SET_STATE qualifier causes the current state to change to
the specified state when you press the key. The /NOSET_STATE
qualifier causes the current state to remain in effect.
2.6 /TERMINATE
/TERMINATE
/NOTERMINATE (default)
Controls whether the specified string is terminated (processed)
when the key is pressed. The /TERMINATE qualifier causes the
string to be terminated when the key is pressed. The /NOTERMINATE
qualifier enables you to press other keys before terminating the
string by pressing the Return key.
3 – Description
Keypad mode must be enabled (SET MODE KEYPAD) before you can use
this command. Keypad mode is enabled by default.
The DEFINE/KEY command enables you to assign a string to a
function key, overriding any predefined function that was bound
to that key. When you then press the key, the debugger enters
the currently associated string into your command line. The
DEFINE/KEY command is like the DCL command DEFINE/KEY.
For a list of the predefined key functions, see the Keypad_
Definitions_CI online help topic.
On VT52- and VT100-series terminals, the function keys you can
use include all of the numeric keypad keys. Newer terminals and
workstations have the LK201 keyboard. On LK201 keyboards, the
function keys you can use include all of the numeric keypad keys,
the nonarrow keys of the editing keypad (Find, Insert Here, and
so on), and keys F6 to F20 at the top of the keyboard.
A key definition remains in effect until you redefine the key,
enter the DELETE/KEY command for that key, or exit the debugger.
You can include key definitions in a command procedure, such as
your debugger initialization file.
The /IF_STATE qualifier enables you to increase the number of
key definitions available on your terminal. The same key can be
assigned any number of definitions as long as each definition is
associated with a different state.
By default, the current key state is the DEFAULT state. The
current state can be changed with the SET KEY/STATE command,
or by pressing a key that causes a state change (a key that was
defined with DEFINE/KEY/LOCK_STATE/SET_STATE).

4 – Examples
1.DBG> SET KEY/STATE=GOLD
%DEBUG-I-SETKEY, keypad state has been set to GOLD
DBG> DEFINE/KEY/TERMINATE KP9 "SET RADIX/OVERRIDE HEX"
%DEBUG-I-DEFKEY, GOLD key KP9 has been defined
In this example, the SET KEY command establishes GOLD as
the current key state. The DEFINE/KEY command assigns the
SET RADIX/OVERRIDE HEX command to keypad key 9 (KP9) for the
current state (GOLD). The command is processed when you press
the key.
2.DBG> DEFINE/KEY/IF_STATE=BLUE KP9 "SET BREAK %LINE "
%DEBUG-I-DEFKEY, BLUE key KP9 has been defined
This command assigns the unterminated command string "SET BREAK
%LINE" to keypad key 9 for the BLUE state. After pressing BLUE-
KP9, you can enter a line number and then press the Return key
to terminate and process the SET BREAK command.
3.DBG> SET KEY/STATE=DEFAULT
%DEBUG-I-SETKEY, keypad state has been set to DEFAULT
DBG> DEFINE/KEY/SET_STATE=RED/LOCK_STATE F12 ""
%DEBUG-I-DEFKEY, DEFAULT key F12 has been defined
In this example, the SET KEY command establishes DEFAULT as
the current state. The DEFINE/KEY command makes the F12 key
(on an LK201 keyboard) a state key. Pressing F12 while in
the DEFAULT state causes the current state to become RED. The
key definition is not terminated and has no other effect (a
null string is assigned to F12). After pressing F12, you can
enter "RED" commands by pressing keys that have definitions
associated with the RED state.
